State urges caution as algal bloom continues in Fontana Lake

Officials with the state Division of Water Resources are reminding people to avoid contact with a potentially a harmful algal bloom that continues to grow in parts of Fontana Lake.

First observed in the Tuckasegee arm of the lake in early August, the bloom was reported below the Bryson City 288 boat ramp, mostly along the shoreline but visible out into open water. Under current conditions, blooms may be present in other parts of the lake.

Laboratory analysis of water samples indicate the bloom is filamentous bluegreen algae. The algae species have been identified as Aphanizomenon and Anabaena, which may produce toxins and pose a potential health risk. Water quality specialists with the division’s Asheville regional office will continue to monitor conditions at the lake.

North Carolina has had no reports of adverse health effects in people associated with this algal bloom.

While it is safe to boat or fish in the affected areas, state health officials routinely encourage the public to avoid contact with large accumulations of algae and prevent children and pets from swimming or ingesting water in an algal bloom.

State health and water quality officials suggest the following steps to safeguard pets and children from any potentially harmful algal bloom:

Keep children and pets away from water that appears bright green, discolored or scummy. Do not handle or touch large mats of algae.

Avoid handling, cooking or eating dead fish that may be present.

If you come into contact with an algal bloom, wash thoroughly.

Use clean water to thoroughly rinse off pets that may have come into contact with an algal bloom.
